The Islamic State has recruited thousands of supporters in the United States, far more than previously thought, according to a scathing new report, raising the likelihood that supporters of the terrorist army could be plotting attacks similar to those carried out in Paris.

And the “challenges of screening incoming refugees” from Muslim countries may be adding fuel to the fire, according to the report, authored by national security experts at theThreat Knowledge Group.

The report accuses Obama of “downplaying” the threat of ISIS while adding to the threat by importing Muslim refugees that are difficult to screen.

The U.S. has imported 70,000 refugees per year for many years, more than half of them from Muslim-dominated countries such as Somalia and Iraq with active jihadist movements, and President Obama has pledged to increase that number to 85,000 this year and 100,000 the following year.

The new study is significant because the Obama administration has in the past made statements that “around 200″ Americans had left the country to join ISIS and could come back at any time using their American passports.

he White House sent out a stern warning to states about the refugee battle, saying governors don’t have the power to block the federal government from resettling the migrants and attempts to do so could lead to punitive action.

The warning came via a two–page letter from the Office of Refugee Resettlement signed by director Robert Carey, and was first reported by the Houston Chronicle. And it sets the stage for a dramatic Tenth Amendment showdown, pitting states’ rights against the federal government at a time when immigration – underscored by recent terror attacks in France – has moved to top of the list among voter concerns.

14 ‘But if you do not obey Me, and do not observe all these commandments, 15 and if you despise My statutes, or if your soul abhors My judgments, so that you do not perform all My commandments, but break My covenant, 16 I also will do this to you: I will even appoint terror over you, wasting disease and fever which shall consume the eyes and cause sorrow of heart. And you shall sow your seed in vain, for your enemies shall eat it. 17 I will set My face against you, and you shall be defeated by your enemies. Those who hate you shall reign over you, and you shall flee when no one pursues you. (Leviticus 26:14-17)

25 The sword shall destroy outside; There shall be terror within (Deuteronomy 32:25)

12 “Cry and wail, son of man; For it will be against My people, Against all the princes of Israel. Terrors including the sword will be against My people; Therefore strike your thigh. (Ezekiel 21:12)
